What you still need

Optional upgrades & setup details
Optional upgrades
For portable use, choose Plan C instead. A USB power bank is optional, but its low-current behavior must suit the radio; it is not included or required for this desk setup.
After it arrives
Install the Seeed Studio Xiao S3 Wio Bluetooth Companion build, then pair and apply the ATW settings. It ships as a Meshtastic kit; changing the radio frequency alone does not make it MeshCore.
Delivered range allows for estimated standard shipping and sales tax. It is not a checkout quote. Existing phone/computer, tools and site work are excluded as described above.
